"We're all in this thing together," Vaughn said. "The thing for me is I'll let my players talk [as long as] one person talks at a time so we all respect each other and we all listen to each other."

Potential tandem

Shooting guards Arron Afflalo and J.J. Redick play the same position, but Vaughn expects to experiment with playing them simultaneously in the weeks ahead.

"I haven't ruled out any scenario," Vaughn told reporters. "The great thing is you'll probably see that scenario in the preseason and you'll be able to ask me what I think about it."

Vaughn said he hasn't made any preliminary decisions on what his rotations will look like, adding he has asked his lead assistant coach, James Borrego, to set the rotations for practices and "mix it up every day."

Stopping flopping

The NBA announced the specifics of its anti-flopping initiative Wednesday. Potential flops will be reviewed remotely on video, and a player who is determined to have flopped will receive a warning after his first violation.

After that, players will receive a $5,000 fine for a second violation, a $10,000 fine for a third, a $15,000 fine for a fourth and a $30,000 fine for a fifth. A player could receive a bigger fine or a suspension for his sixth violation.

In a statement, Billy Hunter, the union's executive director, said: "The NBA is not permitted to unilaterally impose new economic discipline against the players without first bargaining with the union."

Rookie watch

Nicholson and Kyle O'Quinn have made an impression on Vaughn, but the coaching staff also is schooling the two draft picks in some of the most basic elements of the NBA game. During a recent practice, coaches made sure they spoke to Nicholson and O'Quinn about the three-second rule and what's legal in the low post.

"You don't take those things for granted, whether it's timeouts at the end of the game, advancing the ball the last two minutes of the game," Vaughn said.

Nicholson and O'Quinn, like all rookies, face a learning curve.

During Wednesday's early evening scrimmage, Nicholson threw a pass to an open man — showing good vision in the process — but the pass was just a half-second too late and an opponent intercepted the ball. He'll need to make quicker decisions in the future.

"He'll learn that," Vaughn said. "He's a bright young man."

O'Quinn is developing a reputation as a gritty player, and he outran all his teammates on an end-of-practice sprint Wednesday morning, an impressive accomplishment for a 6-foot-10, 240-pound big man.

Richardson ill

Wing Quentin Richardson didn't attend the morning or evening practices because he was sick, Vaughn said.
